Enrollment support is in gnome-about-me, available in the control-center package in rawhide.

Fingerprints can be used for authentication in gdm and gnome-screensaver.

Detailed Description

Currently, using Fingerprint readers is a bit of a pain, and installing/using fprint and its pam module take more time than should ever be necessary. The goal of this feature is to make it painless by providing all the required pieces in Fedora, together with nicely integrated configuration.

Benefit to Fedora

Better Out-of-the-box experience for systems with fingerprint readers.
Fedora will support one more piece of frequently found hardware.

Scope

Better integration would mean

Having a D-Bus service for handling reading/using the fingerprint reader.

The PAM module uses the VerifyStart method provided over D-Bus to authenticate users, and will be added to the default configuration.

gnome-about-me would use the EnrollStart method to write a new fingerprint data file for the specified user.

gnome-screensaver would be able to use finger scans to unlock the desktop

Any other dialog presented to the user for authentication would be able to use finger scans, e.g PolicyKit

The create-user dialog in firstboot or its replacement could offer to enroll the new user

How to test

Person installs a laptop/desktop system with a fingerprint-reader that's supported by fprint. A good way to find information about your fingerprint reader is to scan the output of lshal for 'Fingerprint Reader'.

Person sets their fingerprint in gnome-about-me

Person can log in using their fingerprint, and the session behaves the same whether logged in with password or fingerprint. In particular, gnome-keyring-daemon is running in both cases

Person deletes their fingerprint in gnome-about-me

Person can no longer log in with their fingerprint

Another thing to test: turning fingerprint support off in authconfig prevents login with fingerprint, but keeps the fingerprint data, so that turning it back on doesn't force people to re-enroll.

To install the necessary packages to test this feature, on a stock Fedora 10 machine, run:

Release Notes

Fedora 11 supports authentication using fingerprint readers. Before you can log in using your fingerprint,
you need to enable fingerprint authentication in authconfig (System → Administration → Authentication)
and enroll your fingerprint in gnome-about-me (System → Preferences → Personal → About Me). For a list
of supported fingerprint readers, see http://www.reactivated.net/fprint/wiki/Supported_devices.

For upgrades from older versions of Fedora, and if pam_fprint was installed, the package itself as well as the changes to PAM configuration should be removed (unless major changes were done to the files, running authconfig as mentioned above will clear the previous changes).
